Jalv is a simple but fully featured LV2 host for JACK. It runs LV2 plugins and exposes their ports as JACK ports, essentially making any LV2 plugin function as a JACK application.

LV2 port of CAPS, a collection of audio plugins comprising basic virtual guitar amplification and a small range of classic effects, signal processors and generators of mostly elementary and occasionally exotic nature.

FreePats is a project to create a free and open set of GUS compatible patches that can be used with softsynths such as Timidity and WildMidi.

RNNoise is a library that uses deep learning to apply noise suppression to audio sources with voice presence. This package provides an LV2 audio plugin.

siggen is a set of tools for imitating a laboratory signal generator, generating audio signals out of Linux's /dev/dsp audio device. There is support for mono and/or stereo and 8 or 16 bit samples.

Guitarix is a virtual guitar amplifier running JACK. Guitarix takes the signal from your guitar as a mono-signal from your sound card. The input is processed by a main amp and a rack-section. Both can be routed separately and deliver a processed stereo-signal via JACK. You may fill the rack with effects from more than 25 built-in modules including stuff from a simple noise gate to modulation effects like flanger, phaser or auto-wah.

Autotalent is a LADSPA plugin for real-time pitch-correction. Among its controls are allowable notes, strength of correction, LFO for vibrato and formant warp.

This is a PyQT GUI application to dynamically modify Pipewire and Wireplumber settings at runtime, such as quantum. sample rate, latency offset setting, services restart and more. It features side-by-side and graph style connections manager, pw-top wrapper, simple ALSA mixer and jack_delay GUI.

The SoX Resampler library (libsoxr) performs one-dimensional sample-rate conversion. It may be used, for example, to resample PCM-encoded audio.

yabridge is Yet Another way to use Windows audio plugins. It supports using Windows VST2, VST3, and CLAP plugins in plugin hosts as if they were native plugins, with optional support for plugin groups to enable inter-plugin communication for VST2 plugins and quick startup times.

Libmixed is a library for real-time audio processing pipelines for use in audio/video/games. It can serve as a base architecture for complex DSP systems.

AlsaModularSynth is a digital implementation of a classical analog modular synthesizer system. It uses virtual control voltages to control the parameters of the modules. The control voltages which control the frequency e.g. of the VCO (Voltage Controlled Oscillator) and VCF (Voltage Controlled Filter) modules follow the convention of 1V / Octave.

Streamripper records shoutcast-compatible streams. For shoutcast style streams it finds the “meta data” or track separation data, and uses that as a marker for where the track should be separated.

Vamp is an audio processing plugin system for plugins that extract descriptive information from audio data — typically referred to as audio analysis plugins or audio feature extraction plugins.

OpenCore-AMR is a library of OpenCORE Framework implementation of Adaptive Multi Rate Narrowband and Wideband (AMR-NB and AMR-WB) speech codec.

Lilv is a C library to make the use of LV2 plugins as simple as possible for applications. Lilv is the successor to SLV2, rewritten to be significantly faster and have minimal dependencies.

This package provides a simple sound library for C++.

This package provides a python API to read and write MIDI files.

ZToolkit (Ztk) is a cross-platform GUI toolkit heavily inspired by GTK. It handles events and low level drawing on behalf of the user and provides a high-level API for managing the UI and custom widgets. ZToolkit is written in C and was created to be used for building audio plugin UIs, where the dependencies often need to be kept to a minimum.

BS1770GAIN is a loudness scanner compliant with ITU-R BS.1770 and its flavors EBU R128, ATSC A/85, and ReplayGain 2.0. It helps normalizing the loudness of audio and video files to the same level.

This package provides bindings for PortAudio v19, the cross-platform audio input/output stream library.

WildMIDI is a simple software midi player which has a core softsynth library that can be used with other applications.

An easy to use audio filtering library made from webrtc code, used in libtoxcore.

WebRTC-Audio-Processing library based on Google's implementation of WebRTC.
